Quest

ions Are Mentos the only

thing that makes coke

fizz? What inside Mentos makes coke fizz?

What coke is better to

use? Regular or Diet.

Both Mentos and Baking

soda makes coke fizz Mentos has sodium in it

Coke has carbon dioxide

Diet coke causes a better

reaction, and regular coke

makes a big sloppy mess

Mentos Soda Fizz Independent variable –

Mentos Dependent – Coke

Hyp

s

The carbon hydrates

and water molecules

(in coke) will cause the

coke to fizz up. Sodium and Mentos makes it fizz too. With

the three things I'm assuming that the fruit

Mentos will have the

biggest eruption.

Analy

sis

Both Mentos gave same reactions, but both eruptions were quick, short, and not

so much fizz came out. With the baking

soda the eruption started out small and

grew in size and lasted

longer.

Concl

usi

on

My hypothesis was partially wrong, but also

right. The carbohydrates

and sodium worked together to erupt. Both

fruit Mentos and mint

Mentos made the same

height eruption and lasted the same. The

baking soda had a longer

lasting eruption, and was

taller than than the others.
